From 3d99ed60721bf2e108c8fc660775766057689a92 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Fri, 25 Aug 2023 13:26:22 +0200 Subject: firmware: arm_scmi: Extend perf protocol ops to get information of a domain Similar to other protocol ops, it's useful for an scmi module driver to get some generic information of a performance domain. Therefore, let's add a new callback to provide this information. The information is currently limited to the name of the performance domain and whether the set-level operation is supported, although this can easily be extended if we find the need for it.
